VB6850 is capable of streaming qxga raw bayer image data up to 20 fps. the auto-focus mechanism combined with a multi-element lens provides excellent image quality at focus distances from less than 10 cm to infinity. all external components, including the auto-focus actuator drivers, are integrated inside the camera module, apart from two cci pull-up resistors. control of the integrated af driver is via the VB6850 cci i/f yielding straight forward system integration. www.st.com
